Activated OVP Alarm
When the OVP is activated, the power supply output shuts down. The display shows OVP FAULT.
RED alarm LED blinks 1/2Hz frequency.
2.9.3
Under Voltage Protection and Under Voltage Limit
The UVL function prevents output voltage setting below the UVL set value, and prevents an
adjustment of the output voltage below a certain limit.
The UVP function prevents power supply operation, if the output voltage is below the UVL set
value. Upon detection of an Under Voltage condition, the power supply output will shut down. The
combination of the UVP/UVL and the OVP functions, enables the user to create a protection
window for the sensitive load circuitry.
Setting the UVP/UVL Mode and Level
The UVP/UVL can be set when the power supply output is Enabled (On) or Disabled (Off).
UVL setting value is limited at the maximum level to approximately 5% below the Output Voltage
setting. Attempting to adjust the value above this limit will result in no response to the adjustment
attempt. The minimum value setting is zero. UVP must be turned "ON" to be operational.
1.
Press the PROT button. PROT (GREEN) LED illuminates.
2.
Rotate the Voltage encoder until UVL appears on the Voltage display.
3.
Rotate the Current encoder to set the required UVL level.
4.
Press the current encoder to select the required level. The display blinks once to acknowledge
the setting.
5.
Rotate the Voltage encoder until UVP Appears on the Voltage display.
6.
Rotate the Current encoder to set UVP ON/OFF.
7.
Press the Current encoder for selection. The display blinks once to acknowledge the setting.
8.
Set the UVP delay time by rotating the Voltage encoder until UVP.DL appears.
The delay can be set by the Current encoder between 0.1~25.5sec.
9.
Press the Current encoder to select the required delay.
The display blinks once to acknowledge the setting.
10.
Exit the PROT menu by pressing the Back button or the PROT button.
